Which of the following is part of the Indoor Environmental Quality category?

The correct choice focuses on Indoor Air Quality Management, which is a key component of the Indoor Environmental Quality category. This category aims to enhance the overall living and working conditions within a building by ensuring that the air quality is healthy for occupants. Effective indoor air quality management includes strategies such as proper ventilation, the use of low-emitting materials, and the implementation of air filtration systems to reduce pollutants and provide a healthier indoor environment.

In the context of LEED certification, achieving credit in Indoor Air Quality is vital as it directly impacts the health and well-being of building occupants. This involves monitoring and controlling pollutants and ensuring fresh air circulation throughout the space, thereby contributing to a comfortable and productive environment.

Other options pertain to different categories within LEED. For instance, water usage monitoring relates to water efficiency, outdoor space design relates to site sustainability, and sustainable site selection focuses on the environmental impact of the building site. Each of these plays an important role in overall sustainability but does not fall under the Indoor Environmental Quality category.
